Interesting stuff. I wouldn’t mind hearing more metallurgy explained.

Building a skid for my machine. The tubing hadn’t come in yet, so I’ve been working on the plasma cut parts.

Not sure if this was your issue, but the air inside the part can get hot enough to build pressure and push your puddle out when you’re trying to seal it up.

Yeah he said he would fail guys that walked the cup. He thought it made for shallow penetration and lack of fusion between passes. In theory, he makes sense, but I don’t think it actually is applicable in the field. Mostly sounded like he had an opportunity to throw his weight around.

I got that email too. Guess I didn’t even look closely at it. They must think it’s alright lol. I’ll probably stick to 2% lanth and layzr.

I don’t do much aluminum, and when I do, I only have tig. But there’s a lot of good useful info in here. Thanks.

I was listening to a podcast the other day. They had a man named Bill Newell on, and he was absolutely death on walking the cup. Something about lack of fusion between passes, from sharpening the tungsten down to a needle and tipping the torch way back. I can kind of see what he’s talking about, but I thought it was sort of extreme. Curious about your thoughts and experience.

Check out the CMR Fabrications Eco Scoop. I think they’re about a hundred bucks with a pretty decent lens.

I wasn’t sure if practice was allowed, so this is pretty raw lol. If I redid it, I would clean the edges better so it didn’t suck stuff into the puddle, and probably turn my gas up a little.

The coupon is 2x8, not sure on the alloy.

PrimeWeld 225 at 150 amps, about 70% EN, about 85 hertz. The coupon was on a heat sink. CK 17 torch set up with stubby standard hardware, #8 cup, 20 cfh argon, 1/8 tungsten sharpened to a point. 1/8 5356 filler
